Authored by: ilovezfs <ilovezfs@icloud.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: Richard Laager <rlaager@wiktel.com> Approved by: Robert Mustacchi <rm@joyent.com> Ported by: Tony Hutter <hutter2@llnl.gov> In any pool without the extensible dataset feature flag already enabled, creating a dataset with dedup set to use one of the new checksums would result in the following panic as soon as any data was added: panic[cpu0]/thread=ffffff0006761c40: feature_get_refcount(spa, feature, &refcount) != 48 (0x30 != 0x30), file: ../../common/fs/zfs/zfeature.c line 390 Inpsection showed that feature->fi_feature was 7, which is the value of SPA_FEATURE_EXTENSIBLE_DATASET in the spa_feature enum. This commit adds extensible dataset as a dependency for the sha512, edonr, and skein feature flags, which prevents the panic.
